Greg Scholes and Elisabeth Collini of the University of Toronto's department of Chemistry have made recent decoveries as to how __solar cell__ molecules absorb and move energy. Their research has been published in the international journal of science. Their reasearch is focused on how light initiates certain physical processes at the molecular level, they are also interested in how humans could take advantage of this information. They more specifically looked at conjugated polymers, the scientists of the U of T think that these polymers are the best things to use when building organic solar cells.

Collini states that the biggest challenge is to control the organic solar cells once they have absorbed light. She also says that her experiments suggest that they can gain control of the cells using quantum effects, even under normal conditions.

Scholes says that the enrgy that passes through the molecules by a quantum-mechanical mechanism, instead of random hopping. This descovery will change the way people think in the field, because everyone previously believed that these quantum effects could only happen in low temperatures and in controlled environments.

These inexpensive solar cells have greatly improved medical imaging techniques and could possibly be used to construct lighter and more flexible TV screens.
